tests: replace hardcoded date with dynamic value

[tomas-sucena]

Closes #53

Replace the hardcoded date with tomorrow's string representation in the isPastDate validator test.

fun isPastDate() {
      // get the current date and offset it by 1 day
      val timeFormatter = DateTimeFormatter.ofPattern("dd-MM-yyyy")
      val tomorrow = LocalDate.now()
          .plusDays(1)
          .format(timeFormatter)
          .toString()

      val params = requiredFields.toMutableMap()
      params[param] = tomorrow
      req(params)
          .expectValidationError()
          .andExpectAll(
              jsonPath("$.errors[0].message").value("must be a past date"),
              jsonPath("$.errors[0].value").value(tomorrow)
          )
}

Review checklist

• Behavior is as expected
• Clean, well structured code
• Properly documents API changes in the corresponding controller test
• Contains enough appropriate tests
• Changes are reflected in the Wiki if necessary
